Two imaging and two autoguide cameras
Circumstances will dictate which combination is used.
Setup for simultaneous CCD and DSLR imaging, see Comments below for what works best for what.

Light weight X-Y adjustment for guide scope made today. Small finder for this guide scope is permanently set to its field, used in PHD guiding.
Works perfect for 600 second subs, but slight scope flex seen on 1800 sec shots. Will check diagonal spider next. (1800 s shot www.flickr.com/photos/edhiker/6357301455 )

45 pounds including two cameras is what winds up on my CGEM drive.

BTW - five meteors were seen during the night's Leonid shower, one a Leonid. In 1966, I saw 300,000. One of these days, I'll dig out those tri-X negatives and stack them.
Update: went outside for one minute, saw a Leonid at 4:30am 11/18/09

It's fun to watch the comet move, and it isn't close to us yet - Oct 20th will be closest.
See Oct Sky & Telescope, pg 56.
.
Two weeks after Comet Hartley has its close encounter with Earth, NASA will have a close encounter with the comet. The EPOXI spacecraft (formerly known as Deep Impact) is hurtling toward Comet Hartley now, and on Nov. 4th it will fly 435 miles from the comet's active icy nucleus. The encounter will mark only the fifth time in history that a spacecraft has been close enough to image a comet's core.
Had to crop and sometimes color adjust each frame(clouds). Sixteen of them.

M22 is a very remarkable object. At 10,000 light years, it is one of the nearer globular clusters. Its 32' angular diameter is sligtly larger than the Full Moon.

C/2006 W3 (Christensen): An evening comet visible in small telescopes
This comet begins the month in Aquila at magnitude 9.3. Look for a 4.5' coma.
... 8d moon not far away, Los Angeles light pollution even closer.
Just checked - faintest stars, despite bright sky= Mag16, brightest= Mag 7

First light test using Canon T1i canera and Meade Pictor 216XT stand alone autoguider.
Exposure: 327 sec at ISO 800 .. contrast enhancement exaggerates vignetting.
Seeing not too good with strong winds.
Getting the autoguider working was not easy due to poor manual and hardware issues (fixed and now known).... it is now fun to use!

3- 166 sec Pictor 2nd test IMG9370 Need to pin down remaining trailing. Could be Meade's use of cardboard in mirror cell, need to try with different scope.
I need to build two accessories to get me out of the dark as to what the Pictor 216XT sees and sends to mount. Two day's work, but I have only one day before the dark of the moon weekend. BTW, Pictor documentation stinks.
Work day #1, reduced current consumption from 1000 to 300mA in 216XT. Now leaving to Mt Pinos.

Shown is NGC 404, a small galaxy visible near the star Mirach in the constellation Andromeda. It was discovered by William Herschel in 1784. Mag 11
The galaxy is a small lenticular galaxy. It is located around 10,300,000 light-years away, just outside the Local Group but does not appear gravitationally bound to it. It is notable for being within 7 arc-minutes to Mirach in the night sky, making it very difficult to observe or photograph, granting it the nickname "Mirach's Ghost".
